Hi T.,
Maybe she's extra tired because she's been sick? It sounds crazy but have you tried giving her a nap 2x a day or earlier? Maybe she's overtired? Especially if she's self soothing at night, it might be taking her longer to fall back asleep once she's woken up. It's just a thought.
Otherwise, you might try a warm bath before her bath just to get her in the "mode" and to loosen up any junk in her chest before she heads down for a nap.
Good luck! Messed up naps are the worst!

p.s.
you've made it 2 weeks do not give her that paci, however tempting it may be. She's made so much progress it would be a shame to throw that away!
